Application filed February 29,1904. Serial No. 195.820.

To wil whom, ,i'ntwy con/cern:

Be it known that I, JOHN ROGERS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valve-ags, of which the following is a speciiication. areThis invention relates to ba s 'which are filled through a valve-controlle `opening by means of a tube or funnel. In one wellknown bag of this type the iillingppening is located at one corner and an integral neck extends inward from this opening, servinr as a valve. As ordinarily ,manufactured these filling-openings and necks vary in size and frequently do not Jrit the filling-tube. In my improved bag the end of the bagblank is notched, the corner beyond the notch is turned down, and a line of stitches is run across the end, providing a neck of uniform diameter which extends inward and upward when the bag is turned right-side out.

Referring to the accompanying drawings; Figure 1 is a side elevation of the bag. Fig. 2 is a plan View oi the notched'end of the bagblank, and Fig. 3 is a plan view showing the corner beyond the notch turned down 'and stitched in place.

The bag 1, shown as of clotl, has a fillingopening 2 at its corner and a iiexible neck or tubular extension 3,' serving as a valve, ex

y tending inward and upward from the opening.

In making the bag ne end of the bagblank 1i, which is foldedinside out, is notched at a point 5 near the corner, leaving the pro* jecting neck 3. l This neck is then turned downward upon` the body of the blank and a line oi' stitches 7 is run along the side 8 and across the end Q of the blank, including the notched portion5, completely closing the bag except at the corner and securing the neck in position. The bagr is then turned right side out and is ready for use after sewing a straight seam across the op osite end.

It will be seen that the position of the notch 5 determines both the size of the iill- 'of theusual bacs are often'either toosinall to slip over the 'iilling-tube or so large that they reverse on the tube under the pressure of the stock, thus causing leakage. The po'- sition of the neck, extending inward and u ward from the filling-opening toward tie end of the bag, does not interfere with the ready insertion of the iillin tube or the introduction of the stock, ut insures the prompt and complete closure di the opening when the bag is iilled and reversed. The upward inclination allows the stock to get under the neck while the tube is in place, and as the neck tapers inward there is no chance of stock getting;` into it when the bag becomes full, since the stock immediately closes the inner openingl when the tube is withdrawn.

2. A valve-bag, having its end notched near one corner, the corner portion beyond the notch being turned down and secured to the bag-body, thus constituting a valvular neck of deiinite size, as set forth.
